The ECG findings include: Peaked T waves best seen in the precordial leads, shortened QT interval and, at times, ST segment depression CLINICAL PEARL: If you see an IVCD, think of hyperkalemia.

[8] This may augment transmural heterogeneity of repolarization intrinsic to ventricular myocardium and, as a consequence, prolong the QT and JT intervals on the electrocardiogram (ECG).
